 +Practical PGP: What you need to know to use PGP effectively
 +
 +This introductory tutorial is aimed at people who have never used PGP
 +or GPG before.  It will cover creating a key, what a key really is,
 +signing documents, signing keys, interacting with keyservers, key
 +management, the Web Of Trust and more.  It may even cover encrypting
 +stuff.  This tutorial will be `hands-on' with many practical exercises.
 +It will not cover the mathematical basis for public-key cryptography nor
 +any in-depth discussion of the arcana, though pointers will be provided
 +for those interested in learning more.
 +
 +The tutorial will be followed by a key signing party at our next OCLUG
 +monthly meeting, on Tuesday May 6th.  Our goal is to get more OCLUG
 +members, and the general public, to start signing and encrypting their
 +email.
